Abstract
A 39-year-old woman was diagnosed with myasthenia gravis when she was 8 years old. Although many treatments - such as cholinesterase inhibitors and steroids - had been given to the patient, her condition did not improve sufficiently. As she demonstrated bilateral 3 mm levator function without any eye movement disturbances, bilateral frontalis sling procedures were performed with an autologous fascia lata. One year after the operation, the operated upper eyelids showed symmetrically appropriate heights with good functional outcome. A sling procedure with an autologous fascia lata was suitable for correcting poor levator function of an ocular myasthenia gravis case.
